Abstract :
The development of low power autonomous systems has triggered the research for waste energy recuperation. A micromachined generator has been designed to extract energy from vibrations in the ambient. It consists of an electrostatic transducer which is continuously polarized by an electret. The design of the generator has been optimized towards miniaturization. A prototype has been fabricated.
